Abstract

The invention discloses a modified aluminum profile with a good anti-corrosion effect. The modified aluminum profile comprises an aluminum profile and aluminum profile anti-corrosion auxiliary materials, wherein the aluminum profile anti-corrosion auxiliary materials are prepared from the following components in parts by mass: 60-70 parts of lye, 10-14 parts of potassium permanganate, 15-25 partsof potassium chromate, 15-25 parts of zinc phosphate, 8-18 parts of sodium nitrate, 5-7 parts of a strong oxidizer, 1-3 parts of trace elements, 1-2 parts of rare earth elements, 1-7 parts of a fluorine modified polyacrylate copolymer and 40-50 parts of water. The lye, the potassium permanganate, the potassium chromate, the zinc phosphate, the sodium nitrate, the strong oxidizer, the trace elements, the rare earth elements, the fluorine-modified polyacrylate copolymer and the water are used as auxiliary materials to prepare raw materials, after the aluminum profile is subjected to auxiliary material treatment, stable internal properties and good comprehensive properties such as stretchability, hardness and strength are achieved. The elements with unique properties can be introduced on thesurface of the aluminum alloy to form a surface alloy strengthening layer with excellent performance. The hardness, wear resistance and corrosion resistance of the overall material of the modified aluminum profile are increased by 30% or above compared with a traditional aluminum profile.

Description

technical field [0001] The invention relates to the technical field of aluminum profiles, in particular to a modified aluminum profile with good anti-corrosion effect, and at the same time, the invention also relates to a preparation method of a modified aluminum profile with good anti-corrosion effect. Background technique [0002] The aluminum profile titanium plating process belongs to the coating technology. It adds pre-plating and electroplating process steps on the basis of the conventional titanium plating process. The aluminum profile process is to place the activated plated parts in an aqueous solution of salt and hydrochloric acid for chemical treatment. [0003] In the processing and production of aluminum profiles, the existing prepared aluminum profiles have insufficient stability and overall hardness and strength improvement, and the corrosion resistance and wear resistance are average, which is difficult to meet the use in special environments, and has certain ...
